Therefore,"both leaves `may be .moved simul-itaneously upon theactuation of either leaf. ,y .y

Rising fromthe supporting bar 16;are yery tica'lly disposed pins 21 which extend into.E

5 openings 22 yinthe center rail for permitting thecenter railfto slide vertically relativegto, thevbar 15; yandfthe remaining supnorting bent from the inner end of the lever 25. The

meeting ends of the levers serve to support the same at an angle as shown in Figure 2 of the drawings and provides a loose operative connection therebetween.

Fixed to the underside of-one of the slide Vrails'l'? is an attaching plate 29 to which a swingable plate or arm 30 is hingedly connected as at 31, the said plate being on a plane to overlie the vertical plane of therlevers 24 and 25 as best seen in Figure 8 of the drawings. YThe inner edgeofy the plate 30 is bent downward into a lip 32 for riding over a exible flat spring tongue 33 mounted upon the-stationary bar 15 and `which extends outward beyond the side ofthe bar to kbe disposed in the path of the swingable plate 32. Thepurpose of the spring tongue 33 will be presently explained. y

Assuming that the leaves of the table are in a closed position as shown in Figure 2 of the drawings, and it is desired to extend the same to an open'position lushwith the table top proper 11. The operator proceeds to grasp one of the leaves by the outer edge 34 and proceeds to pull outward thereon. `In Figure 2 of the drawing the plate 30 is resting upon the'outer end of the lever 25 but as the slide rails move outward,` the said plates Vride over the Vlever until it reaches the joints between the two levers 24 and 25 and drop behind the shoulder 35 provided on the inner end of the lever 25. At this point in the movement of the leaves, the same aredis.- posed beyond the edges of the table top 11 as shown in Figure 3 of the drawinggat which time the said leaves are still on a plane below the plane of the table top. Now,` then by pushing inwardly upon either ofthe leaves, y

deem to bethe most desirable embodiment `of my invention, I do not wish `to limit mya reverse movement of the slide rails is produced which causes the stop shoulderl 35 to prevent vor interfere with the movement of the plate 30 therefore continued inward movement of the leaves will cause the plate l 30 to act as a prop which simultaneouslyv 'moves the ,table slide upward and depresses` the coacting levers 24 and 25`s`o that `the leaves 18 move to a position flush with the table top 11. This position of the parts is clearly shown in Figure 5 ofthe drawing at which time the plate 30 is slightly off center to eventually return to a perfectly vertical position and then to a substantially horizontal position during the closing operation. To close the'leaves, thev same are pulled outward low the levelof the tab e top. This position of the plate is clearly shown in Figure 6 of the drawing. VWhen the leaves have been fully returned to `a closed concealed position beneaththe table top",l the parts assume the position as shown in gure 2 and previously described hereinbefore.

From the foregoing description it will be appreciated that I have provided an extension table in which the extension leaves are normally concealed beneath the table top proper and which may be extendedwhen desired to enlargethe area of the table top in order to rise to a plane Hush with the top. With reference to Figure 1 of the drawings it will be seen that'one end vof theI leaf extends to a position beneath` the edge of the table top 11 imparting the appearance of a molding strip and to carri7 out'the design I provide molding lstri s 36 on the o posits sides of the table whicli are supportedb outwardly extending plates or brackets 3 carried by the apron 14. The general appearanceapplied when the leaves are in a folded position is similar to that of an ordinary tableso vas not to detract from the artistic appearance of thev article;

The end aprons 14 are provided with slots through which the leaves 18 and their respective slide rails are movable and for Sealing these slots I provide strips 40 on the vunderside of the leavesl adjacent the outer ends `thereof which are disposed in vertical alinement y,with the walls of the apron when they leaves are in a closed position as shown in Figure 2. ofthe drawing. These strips serve "to seal the space required for the passage o`f the'extension slide rails during movement to extended and retracted position.

While I have shown and described what I liti iis

self thereto` as such changes as may be desi'red may be resorted to without in any way departing from the spirit of the same, and I` therefore wish to make such alterations as may come within the scope of the appended claims.

Having thus described the invention, what A mounted on said side rails, a pivoted lifting member carried by one of said slide rails, a bearing support, land meansl forfbringin'g said bearingsupport into engagement withv Asaid lifting member upon full extension of said leaves beyond the edges of saidtable top to cause said table slide tomove upwardly upon inward movement of said slide rails to cause said leaves to flushly engage the edges of said `table top.

2. An extension table including a fixed table top, a table slide mounted beneath said table top embodying a vertically movable center rail, and a pair of opposedfslidable side rails mounted thereon, table leaves mountedon said Side rails, a pivoted lifting member carried by one of said slide rails, a bearing support, and means for bringing said bearing support into engagement `with said lifting member upon full extension of said leaves beyond the edges of said table top to Cause said table slide to move upwardly upon inward movement of saidfslide rails to cause -said leaves to lushly engage the edges of said table top, and means in the path of `Inovement of said lifting member to support the lifting member for a predetermined interval during movement of the slide rails to mov the leaves to a closed position. y

3. In an extension table, a support, a table slide embodying a pair of oppositelyslidable rails yhaving extension leaves mounted theree on, a pair of levers pivotally eonneotedatv their outer ends to said slide rails and also pivoted intermediate'their ends to said support, the inner ends of said meeting to form a loose operative connection therebetween, a shoulder adjacent the inner end of one lever, a lifting member pivoted tothe underside of one of said slide rails for engagement with said shoulder upon the outward movement of said slide rails, for depressingsaid levers and lifting said table slideupon successive inward movement of said slide rails to cause said extension leaves to be raised to a position flush with said table top.

4. In an extension table, a iixed table top, I

" ay pair of extension leaves slidable beneath Y top upon inward movement of the same y.from

said table top and movable to an extended position therebeyond, and means for lifting Vsame inspaeed relation to the meeting ends of'said levers during a predetermined interval of closing movement. y

In testimony whereof I aiiix my signature.
